We live in a world where the importance of staying vigil and alert is the need of the hour. Gone are those days when finding a burglar was an uphill task. With CCTV cameras lodged in every nook and cranny of your city, it only makes sense that it is of the best quality and that the people know how to choose the right one. After all, in the name of safety, there’s a lot at stake and it’s imperative to understand the importance of what goes behind your CCTV installations and its cable types.

What are CCTV cable types?

Generally, CCTV cable systems come with a number of tools and components. To the layman, it’s rather too confusing. Therefore, it’s important to understand the basics such as what a CCTV is and why opting for the right cable matters.

CCTV or Closed-Circuit Television is defined as the use of video cameras to transmit signal to a particular place. CCTV is used for mostly surveillance purposes bearing crime preventing, safety, monitoring and crime solving in mind. For this purpose, CCTV usually requires cables that would enhance the quality of video signals. For wired surveillance, there are plenty of other options that help in the transmission of better video signals among other functions. Take a look at the functions of each cable and how they are important for CCTVs.

Coaxial Cables:

Having been around for nearly a century now, coaxial cables are still quite relevant in today’s world mainly due to its high property shielding quality. The shielding helps in preventing any interference with the signal. The copper plate in such cables helps in quickening the transmission of data. It’s a lot easier to install, coming in two sizes for CCTVs:

RG-6

This particular cable is made for higher bandwidth, made of copper and aluminum, and for higher frequency. Therefore, it isn’t ideal for indoor CCTVs. It’s a lot heavier than its other types, thus perfect for CCTVs used by city authorities, administrations, police authorities.

RG-59

Similar to RG-6, the RG-59 refers to ‘Radio Guide’ while 59 refers to the diameter size, i.e., .059 and uses a copper plate. This type of cable is recommended for a lower bandwidth, therefore, it’s ideal for CCTV installations particularly suitable for flats, apartments, societies, hotels and other interior, relatively smaller places. Finolex RG59 coaxial cable is a foaming-based dielectric system. With a super gas injected from the foam insulation, the cable thus helps in providing a better quality signal which eventually helps for better surveillance.

Plug and Play / Video Power Cables:

Considered to be a cheaper option, PnP cables are quite straightforward. The CCTV’s power and video runs on one cable with the BNC (Bayonet Neill-Concelman) connectors present on each end. PnPs are ideal for situations that need quick fixing. It does not take a long time to fix and use, and is considered to be quite user-friendly.

Siamese Cables:

Siamese Cables are usually those that have certain power wires attached to them. While they are considered to be quite complicated to handle, it does, however, provide transmission of both data and power at the same time to security cameras. A combination of two cables, it is made up of RG59 and 18/2 cable, the former for video transmission quality and the latter for power purposes. In other words, since RG59 is a coaxial cable, it helps in running the video to the security camera, whereas 18/2 cable helps in the AC/DC power to the camera.

Optic Fiber Cables:

These cables are considered to be the most expensive option, with its installations taking up a lot of time and manpower. While it provides better quality frequency and signal, it still comes at a cost and can be fragile. However, the data and signal transmissions are so high that it outweighs its cons. Perhaps what sets them apart is the fact that they are comprised of glass tubes along with the plastic insulation. This particular cable is usually preferred for professional set-ups as it’s considered too expensive for residential and other places.

Twisted Pair Cables:

This cable, made up of two insulated copper wires twisted around each other, is usually used for audio purposes, but it has been used by many in terms of video surveillance. Bearing its short length in mind, twisted pair cables are easier to install but that can also play to its disadvantage. Signal interference may happen frequently and aren’t as durable as one would expect.

How to choose the right cable for your CCTV?

– The purpose of why you are installing a CCTV system should influence the type of cable you choose. For a professional environment, video signal and quality is of utmost importance. Similarly, if you wish to install a CCTV system in your apartment complex, ensure the right cable is chosen and installed in every corner for better results.
– For CCTV systems, take into account that the copper conductor of your cable type should be 95% of pure copper. For better results, Finolex coaxial cables come with a solid electrolytic grade which comprises of 99.97% of pure copper, made by us in-house. Efficient in quality, this coaxial cable is perfect for CCTV cameras.
– Be sure to understand every cable type’s specifications first. Once you’ve zeroed in your requirements, go for a more optimal choice. Under coaxial cables, RG-59 and RG-6 from Finolex Wires and Cables ensure a distortion-free video transmission.
– While choosing the right cable will require some research, post opting for one, start focusing on the other aspects including location, power supply, connectors, etc.
– Go for something more economical and easy to install. Finolex’s wires and cables come with a number of energy-efficient technologies thus not resulting in a long electricity bill at the end of the month.

In conclusion, each cable type has its own unique uses, prompting you to weigh every pro and con before you invest in them. We hope our handy guide on different cable types and their uses was helpful. Head out to Finolex if you are looking for new electrical and electronic products.
